My. invention relates to internal combustion engines, more particularly to engines of the Diesel or compression-i ition type, and it has for its object to provi e localized transmission means for rotary devices, other than the crank shaft, together with housing and supporting structure for such means and devices.

It has heretofore been the practice, in con-' nection with Diesel engines, to drive the cam shaft, the governor, and the lubricating, fuel feed and water circulating pumps in a distributed manner from the engine, these parts being located Wherever they might be conveniently placed. In accordance with my invention, the cam shaft driving means, the governor, and the pumps are located at one end of the engine, and special housing and supporting structure is provided therefor, the housing structure enclosing engine-driven means for operating the devices referred to. In this way, it is possible to simplify the me chanical problem of driving the various devices; and, incidentally, such devices are not in the way of the engine structure proper.

This and other objects are effected by my invention as will be apparent from the following description and claims taken in connection with the accompanying drawings, forming a part of.this application, in which: Fig. 1 is a fragmentary side elevational view of an engine showing my improved housing structure applied thereto;

Fig. 2 is an end elevation of the engine shown in Fig. 1 viewed from the right;

Fig. 3 is a longitudinal sectional view of the housing construction; and,

Fig. 4 is a transverse sectional view of the housing construction.

Referring now to the drawings more in detail, in Figs. 1 and 2, I show an internal combustion engine 10 having secured to one end a casing 11 for gearing connecting the crank shaft to the cam shaft. A casing 12 is secured to the outer side of the casing 11 and to the outer side of the casing 12 there is secured a casing 13.

As may beseen from Fig. 3, engine-driven means is arranged co-axially of the casings 12-and 13, such means consisting of a crank 1928. Serial No. 263,417.

shaft 14 connected by a coupling 15 to a shaft section 16 carried by the bearings 17 provided in the transverse plate 18 of the casing 13. Bevel'gear 19 is connected to the shaft-section 16 in any suitable manner, preferably in a yieldable way, and it is used for purposes hereinafter stated.

The casing section 12 is provided with an upper opening 21 to receive the inner portion of the governor 22, the governor having a housing 23 arranged to be supported on top of the housing or casing element 12. At one side, the casing element 12 is provided with an opening 24 arranged to receive the inner portion 25-of a supporting bracket 26 for a'water circulatingpump 27. At the. bottom, the casing member 12 is provided with an opening 28 to receive the inner portion 29 of the housing of the lubricating pump 30. Bevel pinions 32, 33 and 34, meshing with the bevel gear 19, are connected to operating'members respectively of the governor 22, of the circulating pump 27, and of the lubricating pump 30.

As already pointed out, the casing 13 is connected to the casing 12; and, as may be seen from Fig. 3, a rabbeted annular connection 36 as well as abutting flanges 37 and 38"'are provided at the adjacent ends of the casing elements 12 and 13. The casing 13 supports a fuel pump 39, the latter having plungers 40 operated by suitable eccentrics 41 carried by the shaft section 16.

The casing 13 is provided with an interior transverse plate 42 having a bearing 43 for the forward end of the shaft section 16. and a cover plate 44 closes the outer end of the casing 13. A booster pump 45 is carried by the cover plate 44 at the outer side of the latter, the booster pump being driven in any suitable manner from the shaft 16 and supplying oil under suitable pressure by the line 46, to the fuel-feeding pump 39.

i From the foregoing, it will be noted that the engine, at 10, is provided with the usual crank shaft, pistons, and cam shaft and that all other moving parts for the engine are carried by the outboard casing construction consisting of the connected casing elements 11, 12 and 13. In this way, it is possible to arrange all of the auxiliary apparatus, for example, the governor, the lubricating pump, the water circulating pump, the fuel-feeding pump, and the booster pump for the fuel pump as a single compact construction at one end of the engine, thereby simplifying the design of the engine as a whole and providing for a reliable and Well-designed driving arrangement for the auxiliary devices. As shown, the casing element 12 is so arranged that the governor, the water circulatmg pump and the lubricating pump are, in effect, radially disposed with respect to the housing 12 so that the actuating members for such parts may be provided with bevel gears meshing withthe single bevel gear 19 011 the shaft member 16. Also, as the governor, the lubricating oil pump and the watercirculating pumps are carried. by the casing member 12 and have casing extensions fit.- ting the openings 21, 24, and 28, respectively, and as the governor and such pumps are driven by the bevel gear 19, it will be apparent that the governor and such pumps may be removed without dismantling the casing or the driving means carried thereby.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shallbe placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

What I claim is: i

1. The combination with an engine having a frame and a transmission mechanism, of a first outboard housing member carried at one end of the frame for enclosing the transmission mechanism;-asecond outboard housing member connected to the outer end of the first housing member; a third outboard housing member connected to the outer end of the second housing member; a governor, a circulating pump, and a lubricating pump supported bythe second housing member and having actuating members extending thereinto; a fuel-feeding pump carried by the third housing member and having actuating means extending thereinto; and engine-drive shaft means extending axially through said housing members and provided with means for actuating said actuating members and means.
